... results, numerical computations based on the A rbitrary- L agrangian- E ulerian (ALE) method were conducted. The reason we choose ALE method is that it is very stable for the computation of the high speed compressible flow. The problem is modeled as a microtube with the wall thickness, t, its thermal...

... equations and reduce them to incompressible form. The Dorodnitsyn–Howarth transformation was initially derived for laminar compressible flow; however, it has been shown that it is also applicable to turbulent compressible flow ( 15 ). A mass-weighted normal distance is introduced in the transformation...
